Amblyopia, also called lazy eye, is a disorder of sight in which the brain fails to fully process input from one eye and over time favors the other eye. [ 1] It results in decreased vision in an eye that typically appears normal in other aspects. [ 1] Amblyopia is the most common cause of decreased vision in a single eye among children and ...
Ophthalmology. Infantile esotropia is an ocular condition of early onset in which one or either eye turns inward. It is a specific sub-type of esotropia and has been a subject of much debate amongst ophthalmologists with regard to its naming, diagnostic features, and treatment.
Esotropia is a form of strabismus in which one or both eyes turn inward. The condition can be constantly present, or occur intermittently, and can give the affected individual a "cross-eyed" appearance. [ 1] It is the opposite of exotropia and usually involves more severe axis deviation than esophoria. Esotropia is sometimes erroneously called ...
When refractive errors in children are not treated, the child may be at risk of developing ambylopia, where vision may remain permanently blurry. [19] Because young children typically do not complain of blurry vision, the American Academy of Pediatrics recommends that children have yearly vision screening starting at three years old so that unknown refractive errors or other ophthalmic ...
Far-sightedness, also known as long-sightedness, hypermetropia, and hyperopia, is a condition of the eye where distant objects are seen clearly but near objects appear blurred. This blur is due to incoming light being focused behind, instead of on, the retina due to insufficient accommodation by the lens. [ 6]
A relative afferent pupillary defect ( RAPD ), also known as a Marcus Gunn pupil, is a medical sign observed during the swinging-flashlight test [ 1] whereupon the patient's pupils dilate when a bright light is swung from the unaffected eye to the affected eye. The affected eye still senses the light and produces pupillary sphincter ...
Specialty. Ophthalmology. Exotropia is a form of strabismus where the eyes are deviated outward. It is the opposite of esotropia and usually involves more severe axis deviation than exophoria. People with exotropia often experience crossed diplopia. Intermittent exotropia is a fairly common condition. "Sensory exotropia" occurs in the presence ...
Leber congenital amaurosis. Leber congenital amaurosis ( LCA) is a rare inherited eye disease that appears at birth or in the first few months of life. [ 2] It affects about 1 in 40,000 newborns. [ 1] LCA was first described by Theodor Leber in the 19th century. [ 3][ 4] It should not be confused with Leber's hereditary optic neuropathy, which ...
